Opponents of plans to dump boulders along a badly eroded portion of San Francisco’s Ocean Beach could gain a week’s reprieve to propose alternative methods of protecting a threatened roadway and a major wastewater pipeline from erosion due to high surf and winter storms.

Although the city’s Department of Public works suggests installing a wall of rocks as an emergency measure to protect the Great Highway south of Sloat Boulevard and the pipeline that carries the treated sewage of western San Francisco out to sea, Supervisor Rossi Mirkarimi – also a member of the powerful California Coastal Commission – said “armoring and revetment are not a good idea.”

Opponents of the rock revetment plan are concerned that it would adversely affect both the environment and the suitability of the area for surfing, but at great expense and without providing a long-term solution to erosion and rising sea levels.

Mirkarimi also indicated he was willing to consider putting off a Board of Supervisors vote on an emergency declaration that would clear the way for swift work on installing the rocks, which some beach users fear will only create erosion on other parts of Ocean Beach.

“I’m OK with it being held off a week,” although he understands DPW’s sense of urgency in seeking to protect the pipeline, Mirkarimi said.

Mirkarimi’s statement went over well at a packed house of more than 100 surfers and neighbors Monday night at the Park Chalet restaurant.

What isn’t clear at this point is how many of Mirkarimi’s colleagues also would support delaying the vote to confirm the emergency declaration. In any case, the wastewater pipeline is such an important piece of city infrastructure that concerns about losing it will weigh heavily with the members of the Board of Supervisors.

Winter storms and high surf have chewed away at Ocean Beach south of Sloat Boulevard, destroying as much as 75 feet of the coastal bluff adjacent to the Oceanside Water Pollution Control Plant. The San Francisco Department of Public Works has declared an emergency because of the erosion, and on Tuesday the Board of Supervisors is scheduled to vote on confirming the declaration.

Ocean Beach spans four San Francisco local electoral districts: Supervisor Eric Mar’s District 1, Supervisor Carmen Chu’s District 4 and Supervisor Sean Elsbernd’s District 7. In addition, District 5’s Mirkarimi is a regional representative on the Coastal Commission, which has wide-ranging jurisdiction over development on the California coast.

Beach Chalet owner Lara Truppelli offered to collect opinions on the fate of the southern part of Ocean Beach and pass them on to the appropriate governmental authorities. She is collecting input at oceanbeach@beachchalet.com.

To directly contact Mirkarimi and the San Francisco supervisors whose districts include parts of Ocean Beach:

I’ve been helping a San Francisco nonprofit organization establish itself on Twitter, and in the spirit of full disclosure I want to explain my relationship with the group.

The nonprofit I’m working with is called the Wild Equity Institute. You can find WildEquity’s Twitter account at twitter.com/WildEquity. Wild Equity’s mission is to build “a healthy and sustainable global community for people and the plants and animals that accompany us on Earth.”

My work with Wild Equity has been done completely pro bono. That is, I received no compensation for it and I have no economic relationship with WEI. I think Wild Equity deserves the opportunity to be on Twitter and part of the reason I chose to help the group is that I previously knew its executive director, but the fact that I helped it get started on Twitter shouldn’t be construed as a blanket endorsement of everything the Wild Equity Institute does.

If you would like to know more about my work with the Wild Equity Institute, or if you are connected with a nonprofit organization that would like to know more about how to get into Twitter without a big investment of funds and staff time, please call me at 415-685-3428.

June 8 is World Oceans Day, which means stories about local beach cleanups and how to choose the most environmentally sustainable fish at the restaurant or market. We’re also hearing a great deal about the perils excessive harvesting by the commercial fishing industry.

But what of the individual saltwater angler – the recreational fisherman (or woman) who fishes for relaxation, for a challenge, for a few tasty meals, or just for an excuse to get out of the house? How can these fishermen pursue their hobby in a way that will help ensure good catches in the future and sustainable fisheries for their grandchildren to enjoy?

Unfortunately, as a fairly regular – if not particularly skillful – fisherman, I know it’s not easy to know when I’m doing the right thing. I undertook a little online research for advice, recommendations and products. What I found was that there’s not enough good information out there. However, I’ve come up with some recommendations based not only on research, but also my own firsthand experience fishing San Francisco Bay and the Pacific Ocean in Northern California.

I don’t want to point fingers or preach to anyone, but I do want to foster a forward-thinking mindset among my fellow fishermen by providing recommendations that will apply to most people in most places. If you have thoughts on what you read here, please leave a comment.

The basics of eco-friendly fishing

The basic foundation of eco-friendly fishing is legal and ethical fishing. Follow this part of the recommendations, and you’ll be well on your way to being an eco-friendly fisherman.

Read up on all rules and regulations for the place you intend to fish and the kind of fish you intend to catch. Most of the time, these rules are aimed at ensuring the long-term health of fish populations, so be sure to follow the regulations.

Never kill a fish if you don’t intend to eat it.

Never deliberately fish for a species when you know the season is closed. Unintended catches are a fact of fishing (and one of the things that keeps it surprising and fun), but going after out-of-season species can put harmful stress on fish that need their energy for migration, spawning or protecting their young. It can also get you in trouble.

Respect marine protected areas and other areas closed to fishing. We may not always like it when a favored honey hole is put off-limits by new regulations. But one of the benefits of many closures is the creation of a “seed” population of fish that can produce young that will be available to catch in other locations.

Don’t hammer the same spots over and over again. In some situations, such as the sandy Pacific beaches of the United States, fish move quite a lot. A spot that was unproductive in the morning may be full of fish in the afternoon. But in other areas, such as rocky seamounts or rocky shoreline, slow-growing fish may spend their whole lives in a very small area. If you change up the spots you visit, you limit the possibility that you’re depleting the fish in a given location.

Pick up your mess. At many of the places I fish in the San Francisco Bay area and the nearby Pacific coast, litter is a significant problem. Cigarette packages, plastic bags, plastic bottles, bits of old line, rubber gloves, broken tackle – I’ve picked up loads of this stuff at some of my favorite spots, and it’s just depressing to find a meticulously cleaned spot littered again later. Don’t be one of Those Guys. Real fishermen clean up after themselves.

Catch-and-release tips

One of the most obvious ways to protect fish stocks is to release fish. But what’s the best way to ensure these fish survive?

Minimize touching fish with gloves, a cloth or even your hands if you intend to release them. Too much handling can remove the protective coat of slime from fish, leaving them vulnerable to disease. If you need to hold on to a fish to remove a hook, devices that grip the fish’s jaw are a better alternative.

Don’t take fish out of the water if you can avoid it. Fish are meant to be in the water, and any time spent on a dry shore, or the deck of a boat or pier, is stressful. Whenever possible, remove hooks while the fish is still in the water.

Use barbless hooks. I know, that little barb provides some reassurance that once you’ve hooked a fish it won’t come unbuttoned and get away. But in my own experience, I mash down the barbs of my hooks much of the time, and I find that the number of times a barb is the make-or-break factor in landing a fish is extremely small. And when I use circle hooks, I’ve never had a fish throw the hook even when there’s no barb. On the other hand, a barb may make it impossible to get a hook out without further injuring a fish.

Use circle hooks when fishing with bait. The point of a circle hook points toward the shank, an arrangement that would seem counterproductive. But in practice, circle hooks are easy to use and make it harder for fish to throw the hook. Best of all, circle hooks hook fish in the corner of the mouth nearly all the time, which means means less injury for the fish and makes it easy to reach and remove the hook.

Use knotless, rubber-coated landing nets. Rubber and rubber-coated nets are gentler on the fish’s slime coat. Some fish, such as halibut, are particularly susceptible to tail rot because their tails are easily split by the cord of traditional landing nets. Rubber, knotless landing nets reduce the possibility that the fish you release today will later die of disease.

Low-impact fishing tackle and other products

Use biodegradable line. Just this weekend, as I was picking a bird’s nest out of my casting reel, I thought about all the line I’ve unintentionally left behind when fishing. That line is slow to break down, and remains a hazard to birds and fish – and an annoying snag for other anglers. Makers of biodegradable lines claim that whereas regular monofilament can take 600 years to break down, their products disappear in about five years. As far as I can tell, these new lines still are available only in limited strengths and quantities, but they seem to provide an attractive alternative to leaving long-lasting line in the water after snags or break-offs.

Use non-lead sinkers. Standard gear for California salmon fishermen used to include big “cannonball” sinkers for trolling, which would be released to fall to the bottom when a fish was hooked. On the sea floor, these balls of lead might not do much harm. But closer to shore, fish and birds can ingest smaller sinkers. Many tackle manufacturers offer alternative sinkers that don’t use any lead at all. They’re a little more expensive, but I like them because they’re harder than lead and I think I can feel the bottom better with these sinkers. There’s at least one tackle manufacturer that takes the alternative sinker to an extreme, drilling holes in rocks. On California’s rocky shores, fishermen have long used small pouches filled with pebbles or sand as cheap sinkers in this tackle-grabbing environment. I’ve sometimes tied up a rock in a bit of cotton kitchen twine for a sinker in these areas, and it works quite well.

Use plain bronze hooks. Corrosion-resistant steel hooks have the advantage of lasting for season after season – or at least, being tolerant of not being rinsed off after being used in salt water. But a bronze hook that’s left in a fish that breaks off quickly corrodes away, leaving the fish free to feed naturally. I’ve looked for bronze circle hooks, but as far as I can tell these aren’t made.

Other products and practices for eco-friendly fishing

Use locally sourced bait when possible, and avoid non-native bait species. Live baits can carry parasites or diseases, or come packaged with materials such as seaweed that can harbor other organisms and unintentionally introduce them to your fishing environment. Locally sourced baits don’t have to be transported by air, truck or boat, and local fish already are used to feeding on them.

What about bait vs. lures? Some sources I found when researching eco-friendly fishing suggested that bait is better than lures because baits are biodegradable, whereas a lost lure means a chunk of metal or plastic left in the environment. That’s a good point, but I find that unless I’m using circle hooks, fish caught on bait too often swallow a hook deeply, meaning that it’s harder to land and release those fish without permanent harm. I’m not yet sure what I think about this question. However, one way of getting the best of both worlds is with biodegradable soft baits. They can’t replace Kastmasters, diamond bars and other metal lures, but the variety and quality of these products is impressive. And of course, one can always go old-school and carve plugs out of broom handles.

Didn’t get a chance to do more than Tweet in between walking and eating at the Fancy Food Show on Monday, but in case you missed the Tweets from twitter.com/tomprete directly, here they are all together — plus a couple of corrections of my fat-thumb typing.

Heading out for Fancy Food Show in San Francisco. Tweets and liveblog at pretepress.wordpress.com as wireless connections from inside allow. The wireless reception in Moscone Center was flawless.

NextBus on inbound L Taraval wildly inaccurate. Said next train in 17 mins, but actual time was 3 mins. Thanx, NextBus.

Fancy Food Show: OK, mezzeMarin has lured me from the serrano ham with these great little spears of olives, anchivies and peppers. That’s MezzeMarin.

And MezzeMarin’s anchovy fillets are fantastic.

Fancy food show: nice to see a booth of Potuguese stuff, including from Sao George, but naught from Terciera, alas. That’s Portuguese and Sao Jorge.

Fancy food show: Oh, no – Van Vooren foie gras. I’m a goner.

Fancy food show: Fresca Italia gets the beauty prize so far, for its cheeses. Like art.

Fancy food show: This convention is great, but what an environmental downer. Millions of tiny plastic spoons, cups, plates, etc.

… And why does Moscone Center only have hot-water faucets in the restrooms, and only the kind that don’t automatically turn off? The restrooms in the halls were like this, but the restroom in between the two halls of the show did have auto-off faucets.

Fancy food show: wow, Patti LaBelle has a spice mix brand?

Fancy food show: The green/sustainability angle is big, of course, but Gidi is the only booth so far the uses compostable spoons. Kudos. Green themes were trumpteted by a lot of booths, and some of them didn’t have any samples or giveaways at all, so they didn’t use any packaging. But I only found one other booth that used compostable service, and the woman at that booth complained that San Francisco is the only place where people are bothered by the use of so much plastic.

Fancy food show: Just passed Mario Batali. I’m not getting paid so I decided not to throw elbows to get through the throng for a pic. If you count seeing the back of his head and the side of his face, then sure, I saw Mario. I think I caught a glimpse of the clogs, too.

I’m really pleased to report that I’ve almost reached full funding for my story about San Francisco’s Muni express bus service on spot.us!

Muni may be watching its funding get yanked out from under it right now, but that makes it even more important for Muni to run well with the resources still available. And clearly, people are interested in why Muni doesn’t run more expresses to serve the needs of daily commuters. As of the afternoon of Dec. 11, my story pitch for crowd-funded journalism site spot.us was just $60 away from full funding.

One year ago, the container ship Cosco Busan hit a bumper on one of the towers of the San Francisco-Oakland Bay Bridge, spilling more than 50,000 gallons of toxic bunker fuel in San Francisco Bay.

(More following video below)

I went down to Ocean Beach to see the damage for myself, and things were pretty bad. I expected the beach to be completely black with oil, and thought it wasn’t that bad, it was bad enough, with blobs of oil from the size of marbles up to the size of dinner plates all over the sand, and more stuck to the wrack that always rests on the beach.

Oil blob, Ocean Beach

The worst part was the birds. I saw a dead bird covered with oil right away, and farther down the beach I found more that were still alive but heavily oiled and clearly in distress. I think the saddest sight was two little eared grebes hunkered down in the sand near the end of Sloat Boulevard, desperately trying to preen the oil out of their feathers. They likely ingested quite a bit of the oil stuck to them, in which case they probably didn’t survive.

Dead murre on Ocean Beach

One year later, some measures have been taken to prevent another spill and to better clean up afterward, but much more remains undone. A proposed law requiring double-hulled fuel tanks on cargo ships is stalled in Congress, some proposals for faster required response times have been rejected, and most glaringly there still is little training available for people who want to be part of volunteer cleanup crews in preparation for the next spill.

Oiled grebe on Ocean Beach

As for the impact of the spill on the environment of San Francisco Bay and the nearby parts of the Pacific Ocean coast, that’s still under study. One important piece of information will come in just a matter of weeks, when schools of herring make their annual journey into the bay to lay their eggs on eelgrass and various seaweeds. The herring fishery is the last commercial fishery in the bay, with herring eggs (preferably still attached to the seaweed) fetching a good price in Japan.

The pilot guiding the Cosco Busan on the day of the crash is set to go to trial in the spring.

For more photos of the oil spill, including some that the Weather Channel picked up for an episode of its Forecast Earth show, click here to visit my Flickr photostream. I’ve separated some oil spill photos into two folders to make them easier to find.

The San Francisco Chronicle did a good job of covering the Cosco Busan spill when it happened, and they’ve done a good job following up a year later. I don’t see any reason to reinvent the wheel here, so here are some links to my posts from last year, plus some Chronicle stories:

U.S. president-elect Barack Obama has sent clear signals that he intends to move swiftly to start the transition from the Bush administration to his own. However, two areas to which Obama should devote his early attention aren’t traditional priorities: the environment and energy.

Two important policy areas that are almost universally considered urgent priorities for the next president are defense (including domestic national security) and the economy. That makes sense, and of course to run daily business he also needs administrators and advisors such as Rahm Emanuel, an early pick for chief of staff.

But Obama takes office at a time when the environment and energy take positions of great importance, elevating them beyond the second- or third-tier priorites (or lower) they have occupied under earlier administrations. In fact, the environment and energy now are so intimately bound up with the physical and economic security of the United States that I think it makes sense for Obama to address energy and the environment at the same level of importance as national security and the economy.

Obama is in a unique position to do two things if he makes environmental and energy problems top-tier priorities: 1) increase national security by demoting foreign oil to the status of a useful but not critical commodity, by powering more and more of this country with other energy sources (former CIA Director R. James Woolsey goes even further and identifies all oil, not just that from foreign producers, as a security threat), and 2) rejuvenate the economy by making the United States a world leader in the research and development of those viable alternative energy sources.

Whether he sticks with the traditional cabinet structure, creates a new cabinet position, decides to task existing cabinet members with new responsibilities or chooses some other method, the president-elect should act early to address the environment, energy, national security and the economy as a cohesive set of interrelated issues.
